These modules have no impact on consumption metering and can therefore be replaced at
any time without having to destroy the security seal.
Within 30 seconds after mounting (in case of the analog module up to 2 minutes), the meter
automatically detects the module used and is then ready for communication or for
delivering pulses.
The type of module used can be displayed within the service loop (loop 4) based on the
display parameters.
